Ratings for category pages?

Hello! I'm very interested in this option too.This is a very useful feature for Google (microdata) and for users.For example, we have a small category with objects. Users should be able to set their rating for this page.

Hello

there may not be much active in github last days
but there is some intensive work to rework or MVC to use common base classes to reduce the maintenance work in the future

ratings and reviews are now the same thing for us as they are submitted together

Also the design is to allow these in categories too and in other "non Joomla article types" in the near future

but this (rating for categories) will come not in 3.3.0 version 
the feature to allow this for categories will be in some 3.3.x version

I want to notice, that there is no ANY rating plugins for Joomla, which can be used on any page, included category.
All Joomla rating plugins works only in item pages.
So, we have no choice.
Waiting for this option!
